DAVID W. COPELAND, OF SYRAOUSE, NEW YORK.

THILL-COUPLING.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed February 14, 1907. Serial No. 357.320.

To all whom it may concern:

Be it known that I, DAVID W. COPELAND, a citizen of the United States, and resident of Syracuse, in the county of Onondaga, in

the State of New York, have invented new and useful Improvements in Thill-Couplings, of which the following, taken in connection with the accompanying drawings, is a full., clear, and exact description.

This invention relates more particularly to the type of thill-coupling shown in my prior application for Letters Patent Ser. N o. 297,412, filed January 23, 1906.

The object of the invention is to simplify the construction of the couplingespring and its application to its operative position so as to reduce to a minimum the cost of the manufacture of the thill-coupling and also allow the spring to be easily applied and readily renewed in case it becomes necessary to repair or renew the spring. And to that end the invention consists in the improved details of construction hereinafter described and claimed.

In the accompanying drawings Figure 1 -C- denotes the draft-iron which is fastened to the axle by means o1 a clip D in the usual manner. The draft-iron extends some distance from the front of the axle and has its top formed with the recessed semicircular seat -afor the pin -bby means of which the thill-iron --I- is coupled to the draft-iron.

Jwis the cou ling-j aw, which is hinged to the front end o the draft-iron -C- and l is formed with the pin-seat -cand with a rearward extension J 1- terminating in a Vdepression -CZ- in its top.

-f-- denotes the U-shaped spring which has connected directly to one end thereof the link -Z which straddles the draft-iron and overlying rear end of the coupling-jaw -J-. The opposite end of the spring passes through the link -Z and is thereby confined laterally in its operative position. Said end of the spring bears directly on the underside of the draft-iron and is sustained in its position thereon by the link as aforesaid. I preferably terminate said end of the spring with an upwardly projecting tongue -tthe upper end of which bears on the underside of the draft-iron which is formed with. a recess *cat the said bearing.

In case the underside of the draft-iron is convexed transversely, I prefer to form the transverse top edge of the tongue -twith a notch -L- to conform the bearing of the tongue -tto the convexed portion of the underside of the draft-iron as shown in Fig. 2 of the drawings.

I do not limit myself specifically to said form of seat, as this feature admits of modification.

What I claim as my invention is 1. In a thill-coupling of the within described class, the U-shaped spring connected at one end directly to the coupling-link and the opposite end of said spring passing through the link and terminating in an upwardly projecting tongue bearing with its transverse edge directly on the underside of the draft-iron.

2. In a thill-coupling of the within described class, the drafteiron formed with a transverse recess in its underside, and the VU-shaped spring having one end terminated DAVID W. COPELAND.
